Do you need fire rated sealant in St Ippolyts?
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Look out for these signs:
- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
- Gaps flagged on a fire risk assessment
- Linear gaps at the head of walls
If you look after a building such as St Ippolyts Church of England Aided Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- What guarantee comes with the work
- Is the old sealant removed completely?
- Whether you can choose the colour
- How the joint is cleaned and prepared
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
- Assessing a building’s fire safety
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Fire rated sealant in St Ippolyts: local notes
St Ippolyts has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Ippolyts (church of England), gaps around pipes and cables are worth checking after any building work there. For landlords with property near Hitchin station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Include fire stopping when you schedule refits
- Flag any open gap you spot round a pipe or cable
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
Why act early in St Ippolyts
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Around St Ippolyts, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Common questions in St Ippolyts
Is St Ippolyts within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you take on hotel work around St Ippolyts?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed and we can apply it for you.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
How long does the job take?
Most jobs take a few hours for a handful of gaps, and longer for a whole building, including the preparation. We’ll confirm how long when we quote.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
